Name that squeel

<< < (2/2)

The Welder:
Hi.
   Had the same problem with a geiuine L.R. belt. tried putting a drop of water on the belt with the engine running, no noise, changed the belt for a serpentine, no noise since. hope this helps.

mac:
Had exactly the same problem, belt dresser cured it but only for short periods, like mentioned earlier clean the belt and pulleys - my tensioner had black deposits which were hardish but easily cleaned off. However this is a common problem and a more expensive belt with a different part number is available, it`s a softer compound. I went down this route and had no further problems.

Budgie:
Check that the tensioner pully is aligned correctly.
Looking from drivers side (RHD) follow the line of the belt as it goes over the tensioner pully and onto the alternator.
If it is slightly out a line then it will cause the belt to slide across the tensioner pully and cause the squeel.
You fix it by putting a thin shim behind the tensioner, where it meets the front of the engine block to pull it back in line.  :wink:
